Abstract
The extrema of the Ginzburg-Landau free-energy functional for p-wave pairing is studied. Using an algebraic and geometric language, the general equation is written for an extremum and study the distinction between inert and non-inert solutions of this equation. Inert critical points of the quartic free-energy functional are shown to remain critical points even if certain higher-order terms are present. A new non-inert critical point is given in analytic closed form. The necessary conditions for the inert critical points to be local minima of th quartic free energy are obtained.Keywords
